Could be the oil pressure sender unit failure or oil pump failure. Have it checked . If it is the oil pump you can severely damage the engine if you keep running the car.

If your car is overheating it means that there is a leak in the coolant system somewhere. A common problem with a car this age is the in car heater core. Also the auxillary cooling fan may not be working. The first thing to do is a pressure test on the cooling system to determine where the leak is, and proceed from there.

Looking for the ignition distributor is quite easy!

Just follow those spark plug cables, at the end of that cables is a distributor, where all the wires are congregated. Accessing it is easy, the manufacturer made everything about ignition to be serviceable in case of problem and maintenance!

For do it yourself repair, you could purchase a service manual, it cost a little but could save you a lot!

Hope that helps you out!

Ac not working.First thing to check is power to the ac .That is when you start the ac does it shows power.If yes then half job is done.Now if there is power then check for the compressor.Is the compressor turning on.If not then ac will have power but will not function as required.Now if the compressor is running but if you get hot air coming from ac then there is a leak in the ac.Check the coolant level.If its low it has to be made full.Get the ac pressure test done before making the coolant full.This pressure test will help you to know whether there is a coolant leak or not in the system. Also get the radiator and radiator cap checked.Also the radiator fan needs to be checked.If the fan is not running then it can be the cause of ac not running or ac running but giving hot air. But in case if there is no power to the ac then its connections has to be checked.In the dash there is main ac connector.This connections has to be checked by meter. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Unfortunately you have bent valves and the cylinder head will have to be removed to replace them. Even at an idle, the engine has enough momentum to turn far enough to catch up to the stationary valves. Sometimes people will actually cause further damage when replacing the belt by turning the cam to get it in the right spot but not realizing that pistons were in the way during the process. Chances are, some valves are ok, but they'll all have to be checked when you get the head off. This is done by pouring solvent into the ports and watching for leakage out into the combustion chamber.
